Having a very strange error when building tutorials Chapter 5 onwards with the Arcball camera on macOS (Catalina 10.15.4 and 10.15.3):
I get a Thread 1: EXC_BAD_ACCESS (code=EXC_I386_GPFLT) in Camera.swift as part of the ArcBall logic. This only pops once the rotation calculation is executed.
Adding print statements in-between those lines fixes this. (can’t post second image in to show; new user)
Curious if anyone has had this problem, it looks like it is a problem from some people?
